Sincerity

Because the air was getting colder and snow had started to fall, Linda and Paul decided to stay at Anne's apartment until the afternoon. They decided to stay at Anne's apartment, because public transportations had stopped operating due to the extreme weather changes. Anne actually allowed Linda to take her car back to the apartment but Linda refused. She insisted on staying at the apartment because she was worried about Anne's condition. Especially now that she was having her period, even if she went back to her apartment, she couldn't make love to Paul. 

Slap!

Anne punched Linda's shoulder. "Watch your mouth, Linda," said Anne annoyed, she really didn't expect Linda to be that vulgar.

"Why is that? I'm serious Anne. I'm on my period, so even if I go back to my apartment, it's useless because Paul and I can't do our favorite sport," said Linda quietly without guilt.
